PLOW-CLEVIS.

SPECIFICATION forming part of Letters Patent N0. 396,474, dated January 22, 1889.

Application filed Octobe1 10, 1888.

T0 all zu7wm z't mag c0ncern:

Be it known that I, OZIA A. ESSIG, a citizen 0f the United Stntes, residing ab Canton, in the county 0f Stark and Stae 0f Ohio, have invented certain new and useful Improvements in PlowClevises; and I do hereby declare that the following is a fu1l, c1ear, and exact description 0f fl1e san1e, refereuce being had t0 the annexed drawings, nmking a part of this specification, zmd to the letters zmd figu1es 0f 10Fe1en0e minked thereon, in whieh Figure 1 is a view 0f a portion 0f t-he frame, showing t-11e hinga Fig'. 2 is a det-ached side view of the reminingkey. Fig'. 3 is a perspective flew. Fig. 4 is a side view showing a portion of the frame removed. Fig. 5 is a det-ached view of the fender. Fig. 6 is a detached view 0f the screw-threaded nut.

The present invention has relation t0 p1owclevises; and its nature consists in the different parts and combin-ation 0f parts hereinafter described, and partioularly poined 0ut in the claims.

Simi1ar letters 0f reference indicate 001 1esponding parts in all the figures 0f the draw- 1ngs.

In the acoompanying drawings, A represents a portion of a plow-bemn, which may be 0011 strueted in the o1din ary manner, reference being had 130 atraehing the different parts 0f the clevis t0 said b"ea=m. The crown-head B is securely attached t0 the fr0nt erforwzn*d end 0f the bemn A in any convenient and well-known manner, and, as shown, i s provided with the neeth 01 cogs a. 'lhe frame properis formed in tw0 sections, C and D. The secoion C is provided With the arm b, and the secon D is p1ofided with he arm c. Said arn1s extend back 011 the beam A, as illusrraied in the drzmvings, and are seeurely held t0 said beam by means of ehe elanq3ingholt (Z. These arn1s b and c are each provided Witl1 apert-ures, whieh are f01 the pu1 pose 01": receiving zmd holding the pins 01 studs e, said pins being located 011 1;he anns f, 0ne 0f these mn1s being f01med integral with each section 0f the frame proper, said parts being so adjusted and arranged 1311a13 when the pins 0r studs e are p1operly entered in their apertures the seetions C and D Will Serial N0. 287,750. (N0 model.)

be securely hinged together, and at the same time bring tl1e short anns f up011 the inner sides of the 10ng arms Z) and c, thereby secure1y holding the sections C and D together when the frame is properly adjusted 130 the beam A.

T0 the frame is secure1y and pivotally attached the draft-1ink E. Said draft-link is 10- cated substantially as illustrated in alle draw ings, and is he1d by means of the clampingholt g. \Vithin draftlink E is located the screw-tlmeaded nut F, said screw-threaded nut being provided with uhe arms 01 extensions h, which 2ue f01 the purpose 0f entering the a;pertures h. The serew G is located substantially as illustraced in he drawings, and is held in pr0per position by means 0f the collars 2'. One-half 0f the aperture through which said serew G passes is formed in each seetion 0f the frame proper.

113 Will be seen that as the screw G is turned inone direction the drafo-link E Will be elevated, an'd when said serew is turned in the opposite direc1 ion said draft-link will be 10W- ered, thereby regu1ating the eutting-depth 0f the plow. It will also be seen 13hat as he draft-link E is elevated 01 lowered the serewth1eaded nut F Will tu1n upon the arms 01 extensions h, thereby compensating f01 the a1e deseribed by the draft-link E ao the point 0f attaehmen t 0 the screw G.

By attaching the sorew G 130 the draft-link E by means of t11e screw-threaded 111112 F, I am enabled to adjust said draft-link no any desired point within the limits of i1as movements, and at the same time securely hold said draft-link at anydesired poiut 0f adjusnment. For the purpose 0f adj usting the frame together Wih the draft-link laterally, thereby causing the p]ow to take more 01 1ess land, 1;]1e tee'oh 01 cogs a are provided, and also the pin 01 key H. The botom 01 10W61 end of 13he pin .or key is provided with the tangs k, said tangs being bent 01 crved, substantially as illustrated, so as to foree the feathei k between the teeth 01 cogs a, thereby seourely locking the frame, together 'With its diifereno parts, at any desired point 0f lateral adjustment. Vhen it is desi1ed to change the 1at era1 adj us1zment, the pin 01 key H is elevaoed, as illustrated in the doted lines, thereby disengging oho foathor 7a from tho teoth 01 eogs a, when 1311e franno is free to be adjustod 1;0 2u1y desired point With1'n the limits of tho crown-head B.

It Will be Seen that by providlng the ourvod tangs 7a and having ono of theso tangs looated upon each side of v1211e bo1t g oho pin 01 koy H Wi11'b0 foroed toward tho tootzh a as tho key is foroed downward zmd zumy from tho teeth as tho key is elevaced.

Tho fonder I is looated substantially LS shown in tho drmvin and is f01 tho purposo of protecing oho sorow G. Tho bottom o1 lower end of this fendmr is hold in propor position by mem1s of tho pins Z and 13110 aperum-es Z. Tho top 01' uppor end of said fendor is seouroly hold in plaoe by means of tho pin Z and the apert-uro Z ono-half of said operture being formed in oaoh sootion of 1110 frame.

F01 fl1o purposo of proventing 1 he pin o1 key H f10m bocoming dotached from nho frmne, zu1d an the smno timo limiting 11116 movements of said pin o1 koy, so as 130 pre vent the tangs k from bocoming dotachod f101n oho olmnping-bolt g, the stop m is providod, said stop being so adjusted that it will strike t-ho top of ehe frame when the feather 7a has bocome disengaged from the toeth a.

It Will be understood that in attaohing the frzune propor 130 a mota1 plowbeam the form of said framo should bo changod so as to C01 respond With tho form of oho menal bezun, and in attaoh'ing the orownhoad to a 1noml beam its form should be ohanged so as to oonform so the fo1m of the motal beam.

Having fully desoribed my invontion, what I claim new, and dos1'1e to seoure by Letters Patent, is

l. The oombination of tho beam A, hzwing attached thoroto the orown-head B, the f1mno formed in wo soctions, C and D, said seotions being hinged togother, t-he draft-link E, pivota1ly attaohed to tho frmne and canying the serow-threadod nut F, zmd the screw G, substan-tially as and for the purpose specified.

2. Tho oombination of Lho sootions O am]. D, the long aarms b and c, oho shor arms f, provided with tho pins 01' studs e, adapted to enter tho apertures in tho mms Z) und c, und a dmftlink, subsfm1tially as m1d for 11]1e purposo spooified.

Tho pin o1 key II, provided with fixe fangs k, in oomlfination \\'i1211 tho orown-head B, provided wi1 11 1.]1o toeth a, and \\'ifl1 the frzuno O D, substuntially as am1 for the purpose spocifiod.

4-. Tl1o combination of the frmno formed in 1;wo soctions, said seot-ions being hinged togethe1, the. draft-link E, pivotal]y attached to said fmmo and carrying the sormv-throaded nut F, the Screw ?r and holt g, substantially as 21m1 fo1 the purposo Set forth.

5. 'lhe combination of 1;]1o fmmo formed in nwo soctions, the fender I, provided,with the pins o1 oxtensions Z and P, the draft-link E, and holt g, and oho beam A, substantially as zmd f0r tho purpose speoified.

In testimony that I claim the abovo I h2wo horeunto subscribod m y 11 mne in Lho prosonoe or' two witnossos.
